Thrilled to announce that Together Fund is investing in Sentra, alongside a16z speedrun! You track results in Jira. Decisions in Notion. Conversations in Slack. But the reasoning, the debates, trade-offs, and context behind why you chose A over B, disappears into what we call "Dark Matter." A decision made in March looks insane by July because no one remembers the constraints that made it smart. I lived this firsthand at Twitter scaling from 800 to 8,000 employees, and at Google while launching AI Overviews to billions at planet scale. The problem isn't process. Process is compensation for something deeper: organizational amnesia. An organization’s "Systems of Record" doesn’t solve this, they encode it. They store what happened, never why. That's why we are investing in Sentra. Sentra is the always-on collective memory that eliminates organizational amnesia by maintaining accurate context for all members and agents, functioning as an operational nervous system. It connects to every channel where work happens, meetings, Slack, email, code commits, docs, calendars, and treats them not as artifacts to search, but as living signals to synthesize. The fleeting and the permanent, unified into a memory that understands. The founding team is built for this: - Jae Gwan Park (CEO): Product-first founder, memory systems research at UofT and MIT - Ashwin Gopinath (CSO): Former MIT professor, created "Reflexion" (NeurIPS 2023), agents that learn from mistakes, 2x founder - Andrey Starenky (CTO): Early Vapi engineer, ex-IBM, built to process enterprise-scale data firehose Together is an operator-led fund. We invest in problems we've lived. This is one of them. Many congrats Jae, Ashwin and Andrey, we are so excited to partner with you!

Talking to users and thoughtfully integrating their needs and wants was woven through everything we did at IDEO—threaded through every prototype and product decision. Reading my colleagues Joanne and Leo's latest work brought that to mind. They describe a future where research runs continuously, with AI agents recruiting participants and instantly surfacing insights. Synthetic personas, carefully trained on consumer signals, mirror human behavior closely enough to extend live studies and compress timelines from weeks to hours. Today user research mostly runs in fits and starts, prohibitively expensive and locked away in dedicated project cycles when it could be a constant companion, seamlessly integrated into the product development process. Joanne and Leo lay out the full vision here: https://lnkd.in/gEUBSG_J

Don't Build a Better Wheat Farm" - Why Defensibility Stakes Are Higher in Deep Tech Just published a new piece on my "Ignore the Confusion" blog, building on thoughtful insights from Eric Ver Ploeg at Tunitas Ventures about startup defensibility. Eric's core thesis: Too many startups pitch like wheat farmers - "huge TAM, slow incumbents, growing market, domain expertise" - but fail to think through long-term defensibility until it's too late. From a deep tech perspective, the stakes are even higher: ** Unlike software, deep tech founders must commit to defensibility strategies from day one - their funding depends on it ** Patent vs. trade secret decisions are often difficult to reverse and shape your entire competitive strategy ** Even "picks and shovels" providers (the tools that make industries more efficient) become commodities without proper moats The key insight that resonates: Defensibility can't be retrofitted. Whether you're building software or deep tech, your moat must be architected into the business model from the start. Thanks to Eric Ver Ploeg for sharing these insights on startup strategy and letting me build on his framework from a deep tech lens.

In the San Francisco Bay Area, founders are relentless about growing and scaling their companies. They spot opportunity, scale through uncertainty, and create companies that redefine industries. Recently, we gathered a group of founders and tech leaders to discuss the intersection of company growth and long-term personal success. Eric S. Yuan, Founder and CEO of Zoom Communications, shared the inspiring story behind his company’s growth and eventual IPO. Eric reiterated that the founders who create the most impact don’t just plan for an exit – they prepare for what comes after. Too often, personal wealth planning lags company growth, and that gap can become costly at the most pivotal moments. The rest of the evening was focused on closing that gap. Our colleagues in Goldman Sachs Investment Banking, Pawan Tewari and Nick Giovanni, shared a candid outlook for M&A and IPOs in this environment, along with important steps founders should take to prepare for a strategic exit. We ended with a conversation around the key considerations for maximizing founders’ personal outcomes. Pre-transaction planning isn’t defensive - it’s opportunistic. Your company’s exit strategy and your family’s long-term planning work should not be done in isolation. When investment banking and private wealth work in sync, founders can cohesively optimize outcomes on all sides of the equation. To learn more about the practical “do’s and don'ts” for founders, we are happy to share our ‘Goldman guide’ for navigating wealth planning, business exists, and IPOs: https://lnkd.in/ewhEGjV3. Thank you, Eric, and to all the founders who joined us at The Battery in SF. On behalf of Goldman Sachs Private Wealth Management and Investment Banking, we look forward to the next conversation.

Last year’s Series A was a milestone, but it wasn’t a stopping point. As proof that we’ve only been moving faster than before, I’m excited to share that Numeric raised a $51M Series B, led by investors like IVP, Menlo Ventures, Founders Fund, and more. Over the past year, we've launched AI-powered flux analysis that accountants actually trust, built out cash management tooling, and worked with some of the best finance teams in the industry. This raise funds what’s next: more AI agent capabilities, building a strong finance data layer, and expanding the team. If you're interested in working on hard problems in finance infrastructure, let's talk. More on the round: https://lnkd.in/gvkWqiDx

The next wave of consumer products will revolve around one thing: taste. With vibe coding essentially leveling the playing field and greatly reducing the barrier to entry, what’s going to stand out at the end of the day is style. AI can now do a lot: read, summarize, speak, think, and it's just starting to take action through the agent layer. But one thing they can’t do is edit itself. You still need the human touch to discern good taste from bad. At the end of the day, the winners will be defined by who understands the consumer best and who knows how to make products fundamentally easier to use. Thanks for the great conversation Akash Pasricha | The Information

Ribbit Capital is leading the Series A for @SafetyKit. Few people in the world are better than David Graunke and Steven Guichard to replace manual risk reviews and trust & safety with AI models. They saw where the world was going in 2023 and already have huge customers relying on them. 🕵‍♀️
